    TextButtonStyle textButtonStyle = new TextButtonStyle();
    textButtonStyle.up = skin.getDrawable("button.up.9");
    textButtonStyle.down = skin.getDrawable("button.down.9");
    textButtonStyle.pressedOffsetX = 1;
    textButtonStyle.pressedOffsetY = -1;
    textButtonStyle.font = white;
    textButtonStyle.fontColor = Color.BLACK;

    buttonExit = new TextButton("EXIT",textButtonStyle);
    buttonExit.pad(20);

    table.add(buttonExit);
    stage.addActor(table);
}

@Override
public void render(float p1)
{
    Gdx.gl.glClearColor(0,0,0,1);
    Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);


    stage.act(p1);
    stage.draw();
}

@Override
public void resize(int p1, int p2)
{
    // TODO: Implement this method
}

@Override
public void show(){


}
@Override
public void hide()
{

}

@Override
public void pause()
{
    // TODO: Implement this method
}

@Override
public void resume()
{
    // TODO: Implement this method
}

@Override
public void dispose()
{
    // TODO: Implement this method
}

}

当我运行应用程序时，只显示一个白色屏幕。该应用程序肯定运行此代码，因为我已通过logcat测试。

我非常困惑为什么没有出现文本按钮。任何帮助将不胜感激。谢谢。

尝试不设置Table的范围，而是使用table.setFillParent(true)。此外，您需要以下列方式实施resize(...)：

public void resize(int p1, int p2)
{
    stage.getViewport().update(p1, p2, true);
}

LibGDX Scene2d.ui仅显示带有以下代码的白色屏幕
